Appeal No. 96-3684
Application 08/318,034
semiconductor materials can be employed to fill the voids in the porous glass. Moreover, Enoki does not
disclose that ZnS is doped with Mn. It appears that ZnS and Mn salts diffuse into the surface layer of
another semiconductor material in the resultant photoconductive particle, namely, CdSe. In addition, the
examiner has not explained why increasing the threshold voltage would have suggested to or motivated
a person having ordinary skill in the art to substitute Enoki’s photoconductive particles for Herron’s
semiconductor.
We further considered the EPSE reference, but we do not find that this reference makes up for the
deficiencies of either Herron or Enoki. Therefore, we find that the examiner has not established a prima
facie case of obviousness of the claimed subjected matter over the combined teachings of Herron, Enoki
and EPSE as suggested by the examiner. Accordingly, we reverse rejection the rejection of claims 10-23
under 35 U.S.C. § 103 over Herron, Enoki and EPSE.
Conclusion
For the foregoing reasons, the examiner’s rejections of claims 10-23 under 35 U.S.C. § 103 are
reversed.
